Answer:
Alex has driven Total of 1400 miles.
Explanation:
Given:
Miles Driven by Alex = 588 miles
Percentage mile driven by Alex = 42%
Solution:
Let the total miles driven by Alex be 'x'.
And given that 42% of the total miles he drive for work, which is 588 miles.
That means x multiplied with 42% is equal to 588.
So framing the above sentence in equation form, we get;

Now we have to remove the percentile.
For this we have to divide 42 by 100, then we get;

Multiplying by 100 on both side, using Multiplication Property we get;

Dividing both side by 42 using Division Property we get;

Hence Alex has driven Total of 1400 miles.
